Annie Simpson, Meghan C. Eyler
2018, Open-File Report 2018-1156
Invasive species are a subset of non-native (or alien) species, and knowing what species are non-native to a region is a first step to managing invasive species. People have been compiling non-native and invasive species lists ever since these species started causing harm, yet national non-native species lists are neither...
